Intangiriro
3. Acide pinacol ester ni ifumbire mvaruganda ifite imiti ya C12H19BO3 nuburemere bwa molekile ya 214.09g / mol.
Kamere:
-Ibigaragara: Amazi adafite ibara cyangwa bikomeye
-Gushonga Ingingo: -43 ~ -41 ℃
-Ibintu bitetse: 135-137 ℃
-Ubucucike: 1.05 g / mL
-Gukemuka: Gukemuka mumashanyarazi asanzwe nka dimethylformamide, dichloromethane, methanol na Ethanol.
Koresha:
- 3, acide pinacol ester nimwe mubahuza byingenzi muri synthesis. Irashobora gukoreshwa nka reagent yo kubaka imigozi ya C- O na C- C, kandi ikoreshwa kenshi nkumusemburo wa C- C ihuza reaction nka Suzuki reaction na Stille reaction.
-Ikomatanya rishobora kandi gukoreshwa mugutegura andi matsinda akora cyangwa ibice, nka aldehydes, ketone na acide.
Uburyo:
- 3, acide pinacol ester isanzwe itegurwa mugukora Pyran hamwe na boron aside acide pinacol munsi ya alkali catalizike. Uburyo bwihariye bwo gutegura bushobora gutoranywa ukurikije ibisabwa nyabyo, kandi uburyo busanzwe bwo gutegura burimo gukoresha sodium borate na pinacol kugirango ubyitwaramo mubihe bya alkaline.
Amakuru yumutekano:
3, acide pinacol ester irashobora kwangiza ubuzima nibidukikije. Gukoresha bigomba gukurikiza uburyo bukwiye bwa laboratoire kandi bigashyirwaho ibikoresho bya ngombwa byo kurinda umuntu, nka gants ya laboratoire no kurinda amaso.
Byongeye kandi, amakuru yihariye yumutekano namabwiriza yimikorere agomba kwifashisha urupapuro rwumutekano rwikigo (SDS) cyangwa ibindi bikoresho byizewe byifashishwa.
